Hmm, might be a good time to dust off the Morse key. :-) I can manage 10W
of real CW, probably around 50W EIRP on the uplink.

That will be a bit impractical for me, I have some antenna gain, but not the
RF power on 70cm. Using more antenna gain on 70 is possible, but I need
somewhere to store the thing when I'm not using it! I'm more likely to make
it on 23cm, as I can manage higher antenna gain, and will be running 10W of
RF (mounted at the antenna so feedline loss will be insignificant).

I hope LEILA is set relatively low, to give those of us at the QRP end of
the spectrum a chance... :)

True... Hmm, I wonder how cheaply I can get hold of a suitable tripod. But
yes, you're right. Then again, if people can't hear the weak VK, then they
should also work on their setups! :)
Time will tell. I may change my plans and get the better downlink gear up
and running first, and knock up a moderate sized 70cm beam for U band
uplink. I'll see after I've got our IRLP node up (which is taking the
time).
Speaking of IRLP, I'll probably use that as a liaison point when I'm getting
up on AO-40. I will be found on Node 630. :-)
